From the given figure, find the value of the following:



(i) sin C

(ii) sin A

(iii) cos C

(iv) cos A

(v) tan C

(vi) tan A

Answer :

(i) Sin C


We know that,



So, here θ = C


Side opposite to C = AB = 3


Hypotenuse = AC = 5


So,


(ii) Sin A


So, here θ = A


The side opposite to A = BC = 4


Hypotenuse = AC = 5


So,


(iii) Cos C


We know that,



So, here θ = C


Side adjacent to C = BC = 4


Hypotenuse = AC = 5


So,


(iv) Cos A


Here, θ = A


Side adjacent to A = AB = 3


Hypotenuse = AC = 5


So,


(v) tan C


We know that,



So, here θ = C


Side opposite to C = AB = 3


Side adjacent to C = BC = 4


So,


(vi) tan A


here θ = A


Side opposite to A = BC = 4


Side adjacent to A = AB = 3


So,
